Also revert the `.bazelversion` file again, as this will enforce a fixed
version, not a minimum version, which does not work well with our BazelCI.

Internally, we rely on clang-tidy to warn about using deprecated declarations.
And for using deprecated declarations within SAPI itself, we should not warn.
Drive-by:
- Fix warning in `mounts_test.cc`

This should fix the build on Debian 10 with LLVM 11.

- Use `--start-group`/`--end-group` linker options
- Drive-by: use `splitlines()` instead of manual `split("\n")[:-1]`

This change introduces an experimental `generator_version` attribute to the
`sapi_library()` rule. Version `1` will select the current interface
generator, which is based on libclang and Python. Setting the attribute to
version `2`, will select the newer interface generator written in C++ that
uses a full clang compiler frontend for parsing. Both emit equivalent header
output, differences in parsing and/or edge cases notwithstanding.
The default, as of now, is still the old version `1` generator.
Note: CMake allows to select the new interface generator globally by setting
`SAPI_ENABLE_GENERATOR`.

This adds a workspace rule that inspects the current system first and
downloads a suitable version of LLVM/Clang from GitHub if it can't
find one. In the latter case, the necessary parts are build from source,
which can take a while (~10-15m, depending on the build machine).
In order to be found, LLVM/Clang system libraries must be version 11
or higher. On Debian/Ubuntu, install `llvm-13-dev` and `libclang-13-dev`.
The new `llvm_config.bzl` implements this logic. It is loosely based on
upstream's https://github.com/llvm/llvm-project/blob/main/utils/bazel/configure.bzl.
Note that due to the way Bazel separates local repositories, we have to
duplictate some of this code.

This will allow us to experiment with (and subsequently migrate to)
changes to the generated API, possibly incompatible ones.
This change should be a no-op for current builds, as there is only
a single version of Sandboxed API.

Use [`direct_headers`](https://bazel.build/rules/lib/CompilationContext#direct_headers)
from the Bazel/Blaze compilation context instead of _all_ transitive headers.
For the clang based generator, this means we don't try to parse
`textual_headers`, which will fail (they are by definition not
stand-alone, after all).

The Bazel build already queries the current toolchain for its system include
directories. This change brings feature parity and is necessary for systems
with unusual include locations.

This removes our own fork of `absl::StatusOr<>`. Sandboxed API still includes
a custom matcher for Googletest, as that is not open source yet. For
compatibility, the `statusor.h` header is still retained and now aliases
`sapi::StatusOr<>` to `absl::StatusOr<>`.

Build macros in earlier versions of Bazel (pre-1.0) needed to specify
targets in a different format, depending from where they were
included/expanded at build time.
For example, a `sapi_library()` macro invocation in one of the directories
under `examples`, always needed to depend on the SAPI main library as
`//sandboxed_api:sapi`. When using SAPI from another Bazel project, the
same macro would have needed to depend on
`@com_google_sandboxed_api//sandboxed_api:sapi`. The `sapi_library()`
macro was thus checking the repository name and conditionally changed
the dependencies. This approach is brittle and as of Bazel 3.1.0 no
longer works.
This CL simple removes the conditional prefix and unconditionally uses
`@com_google_sandboxed_api`.
Tested on Bazel 1.2.1, 2.2.0 and 3.1.0

- Make Bazel config action more robust

These where inadvertently introduced in an internal cleanup change.
This change also removes a C++17-ism in var_proto.h. To make things easier for
downstream projects, we should stick to C++11 for the time being.

The temporary solution for binaries/tests that fully statically linked is to
link against `gflags` using `-Wl,--whole-archive`. This will no longer be
necessary, once Abseil ships with logging. Then we can (finally) use Abseil
flags and use a logging library that does not depend on a different flags
library.

Since the interface generator is invoked via a Bazel macro, it will be
expanded in the embedding context of the project using SAPI, so package access
needs to go through the full workspace root @com_google_sandboxed_api.
This change also modifies the CMakeLists.txt accordingly, as the "external"
subdirectory is no longer needed/wanted.

If using Sandboxed API from an external Bazel WORKSPACE, dependencies can be
imported by declaring the repository and calling `sapi_deps()`:
```python
git_repository(
name = "com_google_sandboxed_api",
commit = "master",
remote = "https://github.com/google/sandboxed-api.git",
)
load(
"@com_google_sandboxed_api//sandboxed_api/bazel:sapi_deps.bzl",
"sapi_deps",
)
sapi_deps()
